enernrc DISPLAY CHART.

Application filed April 26, 1923. Serial No. 634,917.

To all 20 ham it may concern:

Be it known that I, HAROLD W. SLAUSON,

a citizen of the United States, residing at plex folder of card board orthe like; one

portion representing the normal cross-sectional contour of the mass itsimulates and having a foldable port-ion, representing the loss in onedirection when the mass it represents is distorted; the other portionrepresenting the true contour of the mass it represents when deformed,and is so disposed with respect to the first named portion that thedistorted area shall be visible when the folder is closed, leaf-to-leaf.

Referring to the drawings:

Figure l, illustrates the B leaf of the folder which represents theactual contour of the mass when distorted. The A leaf being representedin broken lines, and the disposition of displaced material by massshading. Fig. 2, is a cross section through the folder, on the lineIIII, illustrating the foldable features.

Figure 3; illustrates the A leaf of the folder which represents theoriginal contour. The broken lines represent the folded position of theB leaf whereby the relation of original and distorted contours may bevisualized.

In particularly describing the specific application of my device to aknown object, a typical cross section through a wellknown commercialtype of resilient truck tire composed of vulcanized rubber has beenselected, as a convenient example.

The aspects of the article, as it appears in cross section (normal anddistorted) is reproduced in the form of prints upon the respectiveleaves A and B of the folder;

it being noted that the metallic rim on which the tire is usuallymounted is indicated as 10. The true cross sectional contours of themass, normal, and in distorted relation as ascertained by actual test,are indicated respectively on the leaves A and B. In order thatdiminution of the height of the mass from its normal, as shown by leafA, may be visualized when the leaves are folded together a portion 11 onA has been arranged to fold up flush pitih the lower edge of thedistorted or B By referring particularly to Fig. 3, it will be notedthat the A leaf, illustrates the true normal cross section of thearticle it represents and that the internal void is shown also in anundisturbed state. In Fig. 1, the leaf B illustrates the distorted crosssections of the same article, wherein the displaced material is clearlyshown in mass. shading, and particularly the restricted profile of theinternal void-is emphasized.

Having thus described my preferred form of folder as applied, by way ofillustration, to one specific article what I claim as new therein anddesire to protect by Letters Patcut is:

1. A foldable graphic chart of the character described, comprising,duplex leaves, permanently hinged, one such leaf showing the article itsimulates in a normal physical state, and another leaf showing adifferent physical state when the simulated article is in a deformedcondition.

2. A foldable graphic chart of the character described, comprising,duplex leaves, permanently hinged, one such leaf showing the articlcitsimulates in a normal physical state, and another leafshowing adifferent physical state when the simulated article is in a deformedcondition, said leaves being so arranged that the normal and distortedstates of the identical article may be simultaneously visualized from aView in one direction.

In testimony whereof I afiix my signature.
